2 Proportion Z Intervals!

We're onto chapter 22! We'll finish this all before the end of the week, and you will likely have a take home quiz this (3 day) weekend.

Tonight, please complete the following in your textbook:

Page 507: 1, 3, 4, 5

Also, we have a vocab test on inference for proportions this Thursday! Study!

***Period E***
Since we had our fire drill here's your modified homework:
1abcde (for e try to use your graphing calculator to find the interval and answer this question)
3ab (on calculator) d
4ab (on calculator) d
5ab (on calculator)

In other words, just find all the confidence intervals with your calculator and skip the intepretations.
